Nov. 4, 1930. F. R. HALL APPARATUS FOR EXTRACTING MOISTURE FROM AIRPatented Nov. 4, 1930 UNITED STATES PATENT OFFICE FREDERICK ROBERT HALL,OF ARNCLIFFE, NEAR SYDNEY, NEW SOUTH WALES, AUSTRALIA APPARATUS FOREXTRACTING MOISTURE FROM AIR Application led October 10, 1928, SerialNo.

'A This invention relates to apparatus for removing moisture from air.Its object is to provide apparatus which is of simple and cheapconstruction, readily assembled and disassembled, and effective for thepurpose for which it has been designed.

Referring to the accompanying drawings, Fig. 1 is a broken perspectiveview; Fig. 2

longitudinal sectional elevation; and Fig.

cross-sectional plan view.

A'container 1 of suitable shape is provided; it is preferablyscrew-threaded at its opposite ends. Abfout the head of the container 1is a ange 2.- To such flange is adapted to be fitted a packing washer 3whereby whena cover 4 is screwed to the head of the container 1 thelatter will be air tight at the joints between the cover 4 and thecontainer 1. The

foot of the container 1 is adapted to have 2o screwed thereto a slopingbottom 5 and at the centre of the latter is an'opening 6 communicatingwith a drain cock 7 for water, the said drain cock being furnished witha control valve 8.

Centrally of the cover 4 is an opening 10 about which is situated aflanged union 9 ,the cover 4 is adapted to hold a moist air admissionreceptacle 11 within the container 1, the receptacle 1l being preferablyscrewed to the cover 4. The receptacle 11 hasa series of openings 12 inits side walls.

Surrounding the perforated air admission receptacle 11 is a strainer 13consisting preferably of a piece of wire gauze of appropriate gauge andof spiral form with distance pieces 14 between each of said spiral orcoils. At the head and foot respectively of the strainer 13 is a cup 15.The head cup 15may lbe attached to the cover 4 for the container 1 bymeans of screws 16 and the bottom cup 15 maybe connected to the head cup15 by sta s 17. Said strainer 13 n vtlie 1s carried withi said cups 15.Outlets 18 are provided in the cover 4 of the container lpthrough whichair which has been deprived of moisture or water may pass to a serviceconnection. y' I- InA operation, air containing moisture vor water isled to the 'air'admis'slon receptacleA 11 within the container 1; suchairpasses 311,689, and in Australia November 10, 1927.

through the perforations 12in such receptacle and through vthe wiregauze strainer 13 surrounding the receptacle 11. In its passage throughthe strainer 13 moisture or water is extracted from'the air and suchmoisture is collected in the bottom cup 15 and overflows therefrom tothe sloping bottom 5 of the container l from whence it may be withdrawnat will through the drain cock 7.

The dry air in the container '1 may pass therefrom through the outlets18 in the cover 4 to a suitable service connection.

What I claim as my invention and desire to secure by Letters Patentis 1. Apparatus for extracting moisture from air comprising a container,an air tight cover connected thereto and provided with a centrallthreaded opening and withan opposed threaded opening near the outeredge thereof, a moist air inlet in communication with the centralopening in said cover, a perforated moist air admission receptaclehaving one end threaded and engaged in the central opening and arrangedWithin the container, a strainer consisting of a piece of wire gauze ofspiral form 'within the container and surrounding the said receptacle,means associated with the container forthe passage of water therefrom,and threaded nipple outlets engaged in the other openings in the coverfor the passage of dry air from the container. 1 2. Apparatus forextracting moisture from air comprising a container, an air tight coverconnected thereto, a moist air inlet insaid cover, a perforated moistair admission receptacle within the container, a strainer consisting ofa piece of wire gauze of spiral form surrounding the receptacle, headand foot f cups within therontainer for acconnnodating the upper andlower edges of the strainer, the head cup being secured to the cover,stays for connecting the foot cup to the head cup, distance piecesarranged between the separate spiral coils of the spring, means operablyconnected with the container for. the passage of water therefrom, andmeans connected with ghe containers for the passage of dry air thererom.

f- In testimony whereof I alix lnysignaturo.
